The character sequence ??) is a trigraph and causes the following
clang warning:

drivers/atm/idt77252.c:3544:35: warning: trigraph ignored [-Wtrigraphs]

Clean this by replacing it with single ?.

This looks good to me but I am curious how you say this warning in the 
first place since the main Makefile disables this unconditionally. Did 
you just pass -Wtrigraphs via KCFLAGS or something similar?
